So he's been sleeping in the home half the week for seven years - yet in 2014 is claiming the date of separation was in 2007? That does not compute. There are other means of establishing a date of separation besides who spends the night where which may be more useful. In addition to B-F's suggestions, you may want to consider: Have either of you ever filed your taxes as "separated" rather than "married"? If so, in what year? When did the ex (or you) begin reporting a different address as your residence (for credit card bills, employment, health insurance, etc)?

Well on the days that he was here it was business as usual. We did everything together. We gardened and hung out with our kids. We entertained friends etc.

We both filed our taxes together with our accountant as married right up until 2014. Car insurance, banking, and driver's license reflects same. We also shared a spousal credit card account and he stopped paying the balance this year.

We stopped having "relations" in late 2012 because he disclosed he was having an affair. I went to my doctor and had myself screened for std's. We were trying to "make it work" but I decided to officially walk away this year.
